I don't know what I am going to say will give you ALL hope or pull you into hell again!
My friend, current student, tells me that the REALITY is hub is not all, there are telephone and Alumni interview. For him and his friend, it is!
Let's do some easy experiments to verify.
In Asia, there are two sites for hub interview(70 seats): Shanghai(29 seats) and Mumbai! You know what?
Each year, hbs admits about 20~25 Chinese and half of them are from R1, it means about 12 people.
BUT, Shanghai hub only offers 29 seats. Around Shanghai, there are several sources like Japan, Korea, HONGKONG, Taiwan, and all mainland. I think the first choice for all of them is not Mumba but Shanghai. Then how many seats specifically for mainland Chinese? I assume at most half, 14, right?
Then what is the conclusion? if hub interview is all, it means almost every Chinese who gets interview will get offer. It doesn't make sense. Admission rate is only 50~60%. Thus, the answer is obvious, hub is not ALL.
Thus, let's wait for more!!!
